Displays exasperation at postage? (6)
I believe the answer is:
stamps
This clue might be a double definition.
'displays exasperation' is the first definition.
The answer and definition can be both to do with perception as well as being verbs in their -s form.
Maybe they are linked in a way I don't understand?
'postage?' is the second definition.
(I've seen this in another clue)
'at' is the link.
Can you help me to learn more?
(Other definitions for stamps that I've seen before include "Puts the foot down hard, in temper perhaps" , "Brings foot down heavily onto the ground" , "Tramples" , "Philatelists collect them" , "Items of interest to a philatelist" .)
